Correct Answer. B. Isolate the server and begin a forensic analysis Isolating the server prevents further network contamination or data compromise, and starting forensic analysis helps understand the malware's impact and origin, which is critical for preventing future incidents.
Option A is incorrect because simply shutting down the server might prevent immediate use but does not assist in understanding the threat.
Option C is incorrect because updating the operating system at this stage might interfere with forensic evidence and is not an immediate mitigation step.
Option D is incorrect because notifying employees is important but should follow initial containment and investigation to provide accurate information and guidance.

Documenting that all system checks post-upgrade were completed and no issues were found provides a clear and factual summary of the results obtained from the upgrade process. This confirmation is essential for verifying that the system is fully operational and meets the required standards.
Option A is incorrect because an overview of features does not provide specific results about the upgrade process.
Option B is incorrect as performance metrics, while useful, are more about ongoing evaluation rather than immediate post-upgrade results.
Option D is incorrect because user testimonials focus on subjective experiences rather than a factual summary of the upgrade results.

Correct Answer. A. Create a step-by-step guide of the configuration process used, including the rationale behind each step and the impact on the network This method provides a clear, detailed roadmap of actions taken, making it easier for future technicians to understand both the how and the why of the process, which is critical for applying these steps to similar problems.
Option B is incorrect. While conciseness is valuable, overly brief documentation may not provide enough detail to replicate the process effectively.
Option C is incorrect. Documenting only final settings misses crucial troubleshooting steps that led to the resolution, limiting the educational value of the document.
Option D is incorrect. Ignoring the roles of secondary devices can lead to incomplete understanding and replication of the solution.

Correct Answer. A. The total number of devices currently connected to the WLAN High device load on a WLAN can significantly reduce performance and connectivity speeds for all connected devices.
Option B is incorrect. Bandwidth limits could affect speed but would be consistent regardless of the number of devices.
Option C is incorrect. The security type can affect connection processes but not the speed post- connection.
Option D is incorrect. Proximity to the server room impacts wired connectivity more significantly than WLAN speed, which is more about proximity to the access point.

Correct Answer. A. ip add show dev eth0 The command ip add show dev eth0 (or ip addr show dev eth0) is used to display all configurations, including IP addresses, for a specified network interface, in this case, eth0.
Option B is incorrect. ip link set eth0 is used to change settings of an interface, not to display its IP configuration.
Option C is incorrect. ip route show displays the routing table; using eth0 with this command does not provide valid output.
Option D is incorrect. ip config is not a valid command within the iproute2 suite or Linux.
